A 10 kg toy roller-coaster car is 9 meters above the ground and moves at a speed 15 m/s. What is the total energy of the roller-coaster in kilo Joules(1 kJ=1000J)? Write the answer in 2 decimals.
It is thought that there is at least 4*10^7 kg of uranium-235 that could be minded. The energy available from 1 kg of uranium-235 is about 8*10^13 J.
1. Calculate the amount of energy that the world’s uranium-235 supply could generate.
Suppose one gallon of gasoline produces 1.1x108J of energy, and this energy is sufficient enough to operate a car for twenty miles. An aspirin tablet has a mass of 325 mg. If the aspirin could be converted completely to thermal energy, how many miles could the car go on a single aspirin tablet?
